REVERSING-VALVE.

Specification of Letters Patent.

Patented May 26, ieos.

Application filed July 18, 1907. Serial No. 384,439.

To all whom it may concern:

Be it known that I, ULRICH A. PETERS, a citizen of the United States, residing at Pittsbur in the county of Allegheny and State of ones lvania, have invented a new and useful mprovcment in lteversing- Valves, of which the following is a full,

which inight'warp'under the alternate expansion and contraction, are used. My invention further contemplates the provision of a novel construction in which a direct. connection between the gas box and the'stack flue is impossible, and further in which sealed movable parts are embodied with means for operating the same to admit suificient air to the valve to allow the gas casting with the valve removed.

to be consumed in the furnace.

My invention further and specifically resides in the following features ofconstruction, arrangement and operation to be hereinafter described with reference to the accompanying drawings,- forming a part of this speciiication, in which like numerals p are used to designate like parts throughout the several figures, and inwhich Figure 1 is a view half in top plan of the entire apparatus, and half in plan of the base Fig. 2 is a vertical sectional view through the valve on the line II of Fig. 1. Fig, 3 is a vertical sectional view through the entire apparatus on the line IIII of Fig. 1, Figfli is a sec tional viewthrough a portion of the base casting and the valve, Fig. 5 is a fragmentary elevation of a portion of the valve, and partly in section, and Fig. 6 is a sectional view, partly in elevation illustrating the valve mounting.

In the practical embodiment of my inven-- tion I provide a frusto-conical base casting I 1, having a circular rail 2-at its upper outer edge and provided with circular sand and water seal troughs 3 and 4 at its inner lower edge and adjacent the rail 2-, respectively. The casting 1 'is. further provided with ,a circular base opening Aleading to the reposed openings B and C in its inclined sides loading to the regenerator lines and through which the gases pass alternately to and from the furnace. v

The valve proper 5 comprises a two chambered cylindrical casing divided by an ingenerator stack and with oppositely dis clined wall 5, and provided with outwardly extending segmental hoods, oppositely disposed and leading one from each of said chambers and terminating in openings E and F adapted to be a'lined with the openings B and O of the casting i. The valve 5 is also provided with cover plates 6 extending angularly' upwardly from the base thereof and occupying the space between said hood-S, and with a depending flange 8 entering the sand seal trough 3 ad acent'its lower circular opening G 'alining with the opening A of the casting 1, the outer edges of said hoods and said cover plates being continuously formed with flanges 9 entering the watersealqtrough 4 of the casting 1. along each side the roof with seals 10 for the cover plate 6, and supporting the journals 21 of wheels '7 pivotally mounted therein, and 'by means of which the valve 5 is supported to rotate,- set screws" 15v threaded through a portion of said hoods, serving to adjust said journals 2]. to a proper seating and balanced rotation of the valve.- The hoods are further provided with covered cleaning or. exiosion doors 13, while the, casting l is provided with sand pockets 14 leading intoits sand seal trough 3, having removable covers 14 resting upon the coverplate 6, as shown particularly in Fig. 4 and briefly indicated in Fig. 2. The valve 5 is provided. at its upper edge surroundingit-s upper opening D with a water seal trough 12 into which the flange 12, surrounding the lower opening of the gas box 11, projects, and with a plurality of studs 18 extending outwardly from adjacent said edge, on which brackets 18 are mounted which support the said gas box 11. The valve 5 is rotated in any desired 'nianner as by a bevel gear 16. engaging a The hoods are provided In the further operationof my invention in connection with double re enerator chambers for gas and air, I provi e pivotal levers 20 mounted on the sides of the gas box 11 and provided with a pivotal depending arm 20 having a hooked lower end resting adj acent the rail 2. and adapted toengage a plate 19 extending from the .edge of the cover plates 6 over said rail. Thus the cover plates 6 may be raised slightly from their seal to admit a sufficient quantityof air to consume the gas between the valve. and, the furnace.

Having thus described my invention what I claim is:

1 The combination with a valve having a pair of flanges, of a fixed frusto-conical base plate, having a pairpf seal troughs into which said flanges project, substantially as 'described. i

2. The combination with a valve comprising a two-chambered casing having seg mental flue openings leading from said chamcasing, and a'frusto-conic'al base plate upon bers, of a fixed frusto-conical base plate having oppositely disposed flue openings in its inclined sides, corresponding to said segmental valve openings, substantially as described. i I

3. The combination with a valve'comprising a two chambered casing having segmental flu e openings leading from said chain'- bers", and having top and bottom openings communicating therewith, of a hired frusto-i conical base plate having oppositely disposed flue openings in its inclined sides corresponding'to said. segmental flue openings, and having a central base opening con'ii'nunicating with said bottom 0 ening of said. valve, substantially as 'descri ed.

4t. In a valve of the character described, the combination of a casing having segmental hoods extending therefrom, a pair of cover plates movably mounted between said hoods and extending'angularly upwardly from said which said casing is adapted to rotate. having flue openings to register with said hoods and said cover plates, substantially as described.

'5. In a valve of the character described, the combination of a casing having segmental hoods extending therefrom and forming flue openings, a pair of cover plates movably mounted between said hoods, said casing,

hoods and cover. plates having extending flanges, and a frusto-conical base plate upon which said casing is adapted to rotate, having seal troughs to receive said flanges, and

having flue o enings to register with said hoods and sai cover plates, substantially as described.

6, In a valve of the character described, the combination of a casing having segmental hoods extending therefron'l and forming flue openings, a pair of cover plates movably mounted between said hoods, a base plate upon which said casing is mounted to rotate,

having flue openings to register with said cover plates and said hoods, and means for raising said cover plates, substantially as described. I

7, In'a valve of the character described, the combination of a casing having an inlet and provided with extending hoods forming flue openingstherethrough', of a fixed base plate having openings to register with said flue openings, rollers carried by said casing and traveling upon a portion of said base plate, said rollers having their journals pivotally adjustably mounted upon portions of said casing; and means for adjusting "the same, substantially as described. Signed at Pittsburg, in the county of Allegheny, and State of Pennsylvania, in the presence of two witnesses, this 17th day of July, 1907.
